You may not know this, but the main character in Machete first appeared in the Spy Kids movies. It's true! Okay, so technically, it wasn't exactly the same character, but Danny Trejo played another guy named "Machete" who was the uncle to the titular child agents, and also a spy and inventor himself. He wasn't a bloodthirsty killer, but Trejo certainly made the franchise more awesome simply by being in it -- just as he did in the From Dusk Till Dawn movies, as well as the last two Mariachi flicks. Now he's got his own franchise, with two more Machete movies supposedly on the way, but why is Robert Rodriguez the only one taking advantage of his awesomeness? The man would make a valuable addition to any existing franchise -- here are seven we think should grab him while he's hot.
